NTN 1219 K Self Aligning Ball Bearing
The ZIBOO NTN 1219 K is a self-aligning ball bearing designed for electricians and maintenance technicians who need reliable shaft support in power tool assemblies and test equipment. It accommodates angular misalignment between the shaft and housing, reducing stress on surrounding components during operation. This single unit is supplied new in a box, ready for immediate installation in compatible applications.
Thermals noise and power draw
As a passive mechanical component, the bearing generates no electrical noise and draws no power during use. Operating temperature depends entirely on the host equipment's load, lubrication condition, and ambient environment rather than the bearing itself. Proper lubrication and alignment keep friction low, allowing the bearing to run quietly within the thermal limits of the surrounding assembly.
Build quality and mounting implications
The bearing features a 95 mm bore, 170 mm outside diameter, and 32 mm width with a tapered bore (K suffix) for adapter sleeve mounting on standard shafts. Red finish distinguishes the unit visually in the workshop. The self-aligning design tolerates shaft deflection and housing misalignment, simplifying installation where perfect alignment is difficult to achieve. A three-year parts and one-year labor coverage period applies.

Questions about this item
How is the NTN 1219 K bearing mounted on a 95 mm shaft, and what step is often missed?
The K suffix indicates a 1:12 tapered bore; use an adapter sleeve or withdrawal sleeve and tighten the locknut to the specified torque so the inner ring expands evenly onto the shaft.
What maintenance does the NTN 1219 K self-aligning ball bearing need after installation?
Re-lubricate with a compatible grease at intervals suited to speed and load; inspect seals and running noise during scheduled downtime and replace the unit if clearance or vibration exceeds limits.
Which limit of the 95x170x32 mm bearing appears first during continuous high-speed operation?
The thermal limit of the grease fill is typically reached before the dynamic load rating of the 1219 K size, causing lubricant breakdown and temperature rise.
